following the bugzilla trail, another fix is after bash update, yum reinstall bash

I have another problem, do you know how to save the LCD brightness, because every time
after rebooting, the first thing I have to do is adjusting the brightness.
I have post before, by didn't get an answer.

I remember that after updating something like Dbus, the fn+keys don't work anymore. Is the bug of dbus introduce this problem.

Thanks for the info.

I have the same problem with the brightness control on my HP dv7 laptop. Basically the up/down control displays and the scale does move up/down however the screen brightness (ie. dull) remains the same.
Changing the "brightness" number (I use 3 to 5) fixes the issue and my laptop brightness is back to normal again.

Great job!

Tried a reinstall of bash but that did not work. Not sure why that would work anyway but at least I can control the brightness by putting a number in /sys/class/backlight/acpi_video0/brightness. I only need to set it once and since I only reboot when I get a new kernel the issue is just a minor annoyance. When travelling I just put the laptop to sleep and on wakeup the setting does not change. All users of my laptop (ie wife and son) are ok with a brightness setting of 6.

Awesome! Dell XPS 1702x 3D 1080P GT 555M 3GB here:

thought it was the kernel/init upgrade but was having so success... downgraded bash, instant response from brightness controller. updated bash, instantly unrecognized. reinstalled bash (while updated*) and now i'm up to date with brightness control, should make note of this as I assume it may not be the first time we need to use it!

P.S. I should note that this has no effect without the ' Option "RegistryDwords" "EnableBrightnessControl=1" ' in my xorg.conf under Section "Device".
